Abstract
A method for inhibiting dust formation while feeding coal into a coking chamber, comprising preheating coal and subsequently contacting the coal with an aqueous solution of 30-70% by weight of waste sulfite liquor in amounts of about 0.5 to 1.0 parts by weight of said solution per 1000 parts by weight of said coal.
